After reading reviews for a week I picked this one. Arrived in great shape, easy to unpack and setup, software works amazingly well. I unplugged it and it ran much longer than I thought it would.

Needed 120vac supply to walk around with a Spectrum Analyzer to take radio level readings. The instrument requires 25watts, 200-250ma draw; needed for > two hours if possible. Worked for two and half hours wonderfully, of course the battery was new. Absolutely no radio interference was produced by the unit as measured by the analyzer itself. Not really built for this purpose, but did produce .5AH usable energy. Now use for my computer backup.

- Works as advertised, supports my mid-range PC with dual monitor setup long enough to save, close my work & shutdown when outages/fluctuations occur - power supplied to my devices plugged in remains consistent & entirely uninterrupted - Has lived through over a dozen power flickers & full on outages in my small town which is notorious for frying household appliances with our terrible power company (in southern Ontario, Canada) - Alarm when wall power is lost and UPS has kicked on can be turned off/on - Alarm, when on, is not excessively loud - the word alarm makes you think it will be screaming at you but it's comparable to a microwave button beep, probably a little bit quieter - When alarm is turned off, it still makes a very audible click when kicking on due to external power being cut off, so unless you have closed headphones or are blasting music you'll probably know the power went out if you didn't have any other indicator (like you had your lights off in your room mid-day or something) and can begin shutting your stuff off

This UPS was a great solution to support networking equipment (modem, router, switch) that I installed in my basement. It has lots of outlets and the size of the unit was perfect for mounting on the network wall panel.

I work in music recording/mixing studio environments and am extremely fussy about equipment that generates noise. I'm pleased to say that after several months of continuous use, this Li-Ion APC rack unit met and possibly exceeded expectations. When in ideal conditions, the unit is literally silent. No fan noise, no hum, no buzz. The only time noise has been observed is either when the unit is charging (due to a power failure) where very minimal self-noise is inevitable, or in an under-voltage condition (117V or under) where the internal circuitry activates in order to boost the output voltage. In comparison to APC's own legacy units (ie: 2U 750VA-1500VA lead acid monsters) which I have been using for over 15 years - they had frequent noticeable cooling fan noise, and could produce undesirable self-noise when approaching maximum load. And anecdotally, I have had one or two units fail over the years and drop the load.

Ok, its an UPS, nothing to get worked up about. It just does what it's supposed to do and what Cyberpower claims... 'nuff said. Gives me 16min backup on a phenom II 965 be, 8gig, 4 sata drives, 1 dvd burner, 5 usb in use, 5 fans and 1 card reader. Not to shabby. Using my backup silverstone 500w elements as my antec hcg is made by seasonic and rumor has seasonic APFC units not playing nice with simulated sinewaves. That will be tried another day.

It supplies backup power to the connected devices during storms. We connect our 5G Home Internet gateway to it, so the UPS keeps it running when there is a moment of outage.

I've owned this UPS for several trouble free years and am completely satisfied with it's performance. I bought it when it was first coming to dealers. Newegg didn't even have it listed yet so I got it from another place. With computer (7 fans and single GPU), 42 inch TV, printer, modem, and router, I have 12 minutes of power before it's ready to shut things down. Setup is fairly easy with the software and I prefer to use the on-screen interface rather than the pendant. This thing is super quiet when you are not drawing power from it. I've called technical support before and was always treated with respect, having my questions answered.
